Panning inconsistent between Diagram and ChartView

Hi,

I am currently using a ChartView control (w/ChartPanAndZoomBehavior) and a Diagram control in my application. Apparently, the mechanism for panning is different between the two controls. In the ChartView, you have to right click and drag to pan, but for the Diagram, you have to ctrl + left click and drag. Going between these two mechanisms can be confusing. Is there any way to set the key combination for panning so that it could be consistent between the controls?

Thanks!

Window title should be centered with Office2013 theme

Hello,
when using the Office2013, the window title is left-aligned.
To be consistent with Office 2013 and the RadRibbonWindow class, it should be centered horizontally.

RAD SPREADSHEET IMPORT EXPORT

Hi Team,

Scenario :

I am working with Radspreadsheet , I need to import the csv files in spreadsheet coming as bytes from backend systems , and again after editing I need to export the csv file as bytes to the backend.

Developed for TEST PURPOSE

I imported a CSV file into spreadsheet from my project physical resources folder , I made some changes to that file content .
There is a save button on the wpf page which is exporting the CSV using CSVformatprovider and it is saving the file again to a physical location on my system. Now when I tried to import this updated/saved file using CSVformatprovider import utilty , I am getting some exceptions. [ some tabchange event exception saying object reference not set]

Could you please suggest what to do for this scenario.

RadNumericUpDown - Value format

I have a RadNumericUpDown control that's *typically* used for integer input. However, on rare occasions, there is a need to enter a floating point value with up to 4 decimal digits - the bound property is actually a FLOAT.

I know I can configure the control with "NumberDecimalDigits=4" and it will work as expected. However, I dislike the trailing ".0000" that's displayed when the control is being used to enter INT values, which again, is most of the time.

So, is it possible to configure the control to *allow* decimal digits to be entered, but to not display them unless they exist? So, if I enter an INT, I want it to be displayed as an INT (no decimal digits), and if I enter a FLOAT I want it to be displayed as a float - with all entered decimal digits.

Thanks,

Jeff

Buttons within DropDownItemTemplate

hi,

I added two buttons to the DropDownItemTemplate, one of them will do the select item, and the other one will just do a popup. I found that the click event I added to these two buttons in the template never get triggered except for the "SelectionChanged" event from the RadAutoCompleteBox when I click on the item.

Is there anyway I can get those two buttons to work inside the DropDownItemTemplate?

thanks in advance

Iterating the Grid rows and columns is very very slow

Hi
I am iterating through the rows and columns of the grid view like this :
foreach (var row in radGridView.Items)
{
foreach (var column in HeaderInfo)
{
string sUniquename = uniqueNames[iColumn];
var boundColumn = radGridView.Columns[sUniquename] as GridViewBoundColumnBase;
if (boundColumn != null)
{ string data = string.Format("{0}", boundColumn.GetValueForItem(row));}
iColumn += 1;}}
The thing is that its too slow ...for a grid with say 80k rows it is taking 5 minuted to complete this loop...I guess internally it is building up the rows internally as our grid has virtualization enabled.

Please suggest if something can be done on this.

Cell FillColor

Hello, I'm customizing the cells to have rounded corners. I'm using the code from here. http://www.telerik.com/forums/rounded-cell-corners
Is it possible to to have the selected cell only fill the part with the rounded border, instead of the whole cell. See attached for what the control currently does. You'll see that it bleeds out into the rest of the cell.

Thanks,
Scott

Display specific string for NULL cell value

I'm using RadGridView to display DataTable.DataView collections. In the underlying data, it's perfectly valid for some of the fields to be null. However, rather than simply displaying those fields as a "blank" cell in the grid, I'd prefer to display a predefined string (say, "<null>" for example). Is there an easy way to accomplish this?

One possible restriction on a solution is that the grid is used to display "random" DataView's and auto-generates the columns for each. So, the solution would need to work in that circumstance.

Thanks for any advice.
